Based upon a comparison of percent- ages above, it is assumed that the water- shed was probably composed of 65 to 75 Leiberg had 4 categories: percent mid and late seral forests at any 1. Nonforest Area: This included one time. burned areas, glades, meadows, marshes, lakes, semiarid tracts, etc. 2. Badly burned areas: We as- sumed that these were forested lands that had received some type of fire. They were classified as early sera] stage. 3. Forested Area: included all forested area that contained trees 4 inches in diameter or greater. We classified all these as either mid or late seral stage. 4. Logged Area (None found within this watershed) In order to derive numbers for Table 2-1, we averaged the percentage of land in each c!assifcation stated above for the 8 town- ships surrounding and within the Spencer Creek watershed. The numbers were obtained from Leiberg's description. Note: Later in the analysis process, Leiberg's 1899 vegetation map was digitized just for the watershed boundaries. This later analysis is a better representation of the actual historic breakdown of seral stages in the watershed, but the digitizing was completed so late in the process. that we can only include it in the Appendix. The percentages of the different seral stages is somewhat different that the other method, b 'hey: are still reasonably close.
